USDA's Joint Ag Weather Facility says in the Corn Belt, showers and thunderstorms remain active in the Great Lakes region, but most Midwestern locations are experiencing hot, dry weather. "Monday’s high temperatures topped 95°F in many areas west of the Mississippi River, and will do so again today," USDA reports. On Aug. 25, one-fifth of the soybeans in Iowa and North Dakota were rated very poor to poor, tops in the U.S. and well above the national average of 13%, USDA details.
In the West, USDA reports a plume of tropical moisture stretches from the Desert Southwest to Montana. "Flash flooding remains a threat, particularly from southern California to Utah," USDA says. "Meanwhile, dry weather persists across northern California and the Northwest, where more than two dozen large wildfires are burning," USDA explains. The Rim fire, near Yosemite National Park in California, has blackened more than 160,000 acres and is only 20% contained, according to USDA.
On the Plains, USDA says hot, dry weather prevails, except for a few showers in Montana. "Heat favors spring wheat maturation and harvesting on the northern Plains, but is stressing rain-fed crops on the southern High Plains," USDA continues.
In the South, USDA reports drought-easing showers continue in the western Gulf Coast region. "In contrast, favorably dry weather prevails in the Southeast, except for lingering showers in southern Florida," USDA adds. "On Aug. 25, Florida and Georgia led the nation with topsoil moisture rated 36% surplus," USDA explains. Due to ongoing issues with wetness, more than one-tenth of the peanuts were rated very poor to poor on August 25 in Alabama, Florida and Georgia, USDA explains.
In its outlook, USDA for the remainder of the week, areas between the Rockies and Appalachians will continue to experience a late-season heat wave. "In areas with limited soil moisture, including much of the Midwest, the heat will adversely affect crops in the filling stage of development," USDA reports. Meanwhile, USDA says showers and thunderstorms will continue to rotate clockwise around a ridge of high pressure parked over the nation’s mid-section. "Five-day rainfall totals could reach 1 to 2 inches, with locally higher amounts, in the Southwest and from North Dakota to the central Appalachians," USDA explains. After mid-week, showers will arrive in the Pacific Northwest, according to USDA.
